On systems with STACKTRACE_SUPPORT=n, we get:
WARNING: unmet direct dependencies detected for STACKTRACE Depends on [n]: STACKTRACE_SUPPORT Selected by [y]: - STACKDEPOT [=y]
and build errors such as:
m68k-linux-ld: kernel/stacktrace.o: in function `stack_trace_save': (.text+0x11c): undefined reference to `save_stack_trace'
Add the missing deendency on STACKTRACE_SUPPORT.
